seems reasonable. takes about 10 seconds on the quad xeon to get off
of Qd8, -1.21... by the time it finishes 12 plies in 22 seconds it is
up to +.75 and climbing...

hard to say... seems pretty speculative, although you get the a and b pawns,
plus the e pawn, so material is even, but being down a piece can be tough if
the attack doesn't come to something... Crafty wouldn't play this, but after
10 plies, 9 seconds, it thinks that white is ahead by only .27, so it is a tough
call...
